Hi again.
Another fault that cant be cleared.
Ctrl module faulty - 65535 under in the all wheel drive menu.
When i want to communicate with the haldex module, first time dont let me in, but after worked fine.
Checked the haldex pump and working good. Checked the car in slippery condition and haldex kicking in right away, so what else could be?
I read somewhere, this code can be a faulty airbag system. This is right?
My airbags are all open. I only realized after buyed the car, but its ok.
